durexForth v1.21

Ravelli released a new version of Forth for the Commodore C64. Forth is a very low-level and minimal language without any automatic memory management. Forth on the C64 is faster, more memory effective and more powerful than the standard Basic. Forth on the C64 includes an editor, compiler and assembler. Changes in this version: Updated documentation. The blkcol function has been changed. RESTORE jumps back to editor. Buffer is cleared when loading. Gfx loaded by default. Changes for the “J” command.
